UPS output waveform to see whether it is stable.
• Change the frequency of Ulity to 56Hz, the UPS will switch to Backup Mode automacally.
• UPS will go back to Ulity mode once the Ulity frequency goes back to 50Hz.
• Connect the control wire of the Charger and push the funcon key to execute self-test, then the UPS
will detect this abnormal condion and display baery abnormal on the LCD.
• Use Scroll up key pad and Scroll down key pad to see if any abnormal display content or values on
the LCD panel.
• Push key pad for 5 seconds unl buzzer beeps twice, then UPS will shut o and close the input of Ulity.
• Your UPS Unit test is done completely.
UPS Inverter Output Balance Check
Connect the UPS as shown below
• Disconnect the isolaon transformer if any; otherwise, it is not possible to measure whether the UPS out-
put waveform is in balance or not.
• Connect a 220Vac/50(60)Hz to the UPS to start up the UPS and make sure it is on Line Mode.
• Without output load connected, please connect a xture in parallel.(The xture is made with 1M ohms re-
sistors and 1uF/63V capacitor in serial. Then, measure the two ends of 1uF/63V capacitor to see whether
the DC voltage is below 20mV.
• Connected a 6Kva/4200W resistor load to the output and repeat.
Unit Calibraon and Seng Procedure
General Parameter Seng Procedure
• Please connect the UPS.
• Connect a 50/60Hz 220Vac source to the UPS, start up the Ulity and Bypass breakers on the rear panel as
well the Inverter Switch on the front panel.
• Connect the RS232 cable to the UPS and computer, then execute MSII Seng tool program.(MAKE SURE
THAT THE PROGRAM IS INSTALLED COMPLETELY, BEFORE THIS SETTING PROGRAM IS IN USE.)
